Final answer:
To construct balanced chemical equations, it is essential to follow the law of conservation of mass, ensuring equal numbers of each type of atom on both sides of the equation. The balanced chemical equations for the given reactions are provided using condensed formulas. Lewis structures, which visually display the atoms and bonding, cannot be represented in text format and are therefore omitted.
Step-by-step explanation:
To write two complete balanced equations for each of the following reactions, one using condensed formulas and one using Lewis structures, we will proceed with each reaction individually. Unfortunately, the creation of Lewis structures cannot be visualized in text format, so I will omit them from this explanation, focusing on providing the balanced chemical equations with condensed formulas:
- a) CO(g) + O₂(g) → CO₂(g)
- a) CO(g) + O2(g) → CO2(g) (The reaction is already balanced.)
- b) NH3(g) + HCl(g) → NH4Cl(s)
- b) NH3(g) + HCl(g) → NH4Cl(s) (This reaction is also balanced.)
- c) C6H6(l) + 15/2 O2(g) → 6CO2(g) + 3H2O(l)
- c) 2C6H6(l) + 15O2(g) → 12CO2(g) + 6H2O(l)
- d) NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + 2H2O(l)
- d) 2NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + 2H2O(l) (After balancing, we need 2 moles of NaOH for every mole of H2SO4.)
For each reaction, note that we must follow the law of conservation of mass, ensuring that we have an equal number of atoms of each element on both sides of the equation.
